Berserker (バーサーカー, Bāsākā?) is a Berserker-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order. He is also summoned by Izaya Kii in the Moon Holy Grail War of Fate/EXTRA CCC Fox Tail.



Berserker's True Name is Caligula (カリギュラ, Karigyura?), the third emperor of the Ancient Roman Empire and uncle of the later emperor, Nero. Ruling during the 1st century, Caligula was a beloved, wise ruler, but his later actions gave rise to legends of atrocity. He suddenly "became loved by the moon", having fallen into madness. He then ruled the empire through fear until his assassination a few years later.[1][2]



Berserker is a total sadist engrossed in sadism, seeking to perform atrocities and misdeeds upon all enemies who catch his eye. He is completely unmanageable due to Mad Enhancement, removing any means of self-restraint. Berserker possesses a fondness for both Roma and Nero even in his maddened state, allowing contact with either of them to possibly stop his rampages.[2] His wish to the Holy Grail is "to get rid of his madness". If it could be granted, he would wish to return to that time when he was called a wise king, when he told stories to the child of his little sister, Nero, sitting on his lap... To that time, before the Moon Goddess fell in love with him and filled his body with madness.[1]



The beloved child of his younger sister. His niece. Loves her. She is a blood relative of his, while simultaneously, Nero, being the emperor who took over the next era of Rome back then, is a subject who Caligula ought to love.[1]


The great ancestor. An ally that should also be called the genuine first emperor. Caesar, who realized the foundation of Imperial Rome by accomplishing the Roman Republic’s subjugation, is a subject who Caligula ought to love.[1]


The exalted Divine Founder above all else. The whole Roman world began through his way. Being truly the child of the God of War Mars, even though the likes of “Roman emperors were deified after death” already, they cannot even reach this person’s feet.[1]

He feels an unpleasant presence with Altera.[1]


Fate/Grand OrderEdit

Septem: The Eternal Madness EmpireEdit

Caligula is one of the emperors summoned by Lev that leads the United Roman Empire. When Ritsuka and Mashu arrive in the Singularity, he and his army are assaulting Rome. However, Caligula retreats after he and his army are defeated by the combined forces of Nero Claudius and Mashu. He returns to the palace of the United Roman Empire, but Lev sends him out once again to kill his niece. Caligula soon confronts Nero and the Chaldea group at the Shaped Isle to kill Nero, but he is killed by them.

Do Moon Goddesses Dream of Dango?Edit

Eating dumplings with Caesar, Caligula eventually encounters Ritsuka Fujimaru, Mash Kyrielight, and Artemis. He belongs when Mash says that the dumplings belong to Chaldea and not Rome, saying that the dumplings are round like Caesar. Then, when Caesar fails to convince the group with his dumplings business plan, Caligula joins him to fight the group, though he believes that the group is in the right. After being defeated by the group, Caligula looks inside of the bag of dumplings when Artemis senses someone inside it. Unfortunately, he is cut in half by Altera when he looks inside the bag.

Salomon: Grand Time TempleEdit

He is among the "Septem" Singularity servants that fights against the Demon Gods of the Intelligence Room.


In his interlude Dimming Moonlight and My Precious, Caligula accompanies Ritsuka and Mash to Rome to defeat roman soldiers causing chaos in his niece's, Nero, Rome, and also to fix the historical inconsistency. Upon arrival, Caligula immediately attacks the roman soldiers that dared to devastate his niece's Rome. After driving off the rebellious soldiers, Caligula comments that Nero's Rome is more beautiful than the moon.

Fate/EXTRA CCC Fox TailEdit


Caligula is mentioned by Nero in a my room event. She mentions that he admired Iskandar, much as Julius Caesar did. She recalls how she sat upon his lap and regaled her with tales of old legends, such as the Iliad, Heracles, Ulysses, Perseus, but his passion burned most brightly for tales of Iskandar.


Although extremely close in nature to an Anti-Hero, he has manifested as a Heroic Spirit for an unknown reason. It could either be a "prank from a Divine Spirit that presides over the moon", or possibly the potential demise of human history raising the mentality from the period where he was called a wise ruler, the reason that exists in the shadows of madness.[2]

Due to his Mad Enhancement, his parameters are increased but most reason is lost. Only the mission to expand the Roman Empire and make it prosper is not lost; thanks to it, if an ally approaches him citing Rome a luck check occurs, and if successful he restrains his rampage. If the contact is by a person with ties with Rome the check occurs with a plus. That is to say, if he is approached by the likes of Nero or Romulus he would be able to reliably restrain himself. However, such restraint is just a condition of standby, and it's not like perfect communication becomes possible.[1][2]

Glory of Bygone Days (在りし日の栄光?) is the skill that the memories of the four years when Caligula lived as a wise king don't soften his madness; they actually accelerate it. He obtains a plus modifier to his resistance against mental interference and the like, and he raises his strength parameter temporarily if fighting unarmed, but every time Caligula uses this skill he also suffers damage. The rampaging madness makes his spiritual core grate.[1]

Berserker fights primarily with his fists. His Noble Phantasm is Flucticulus Diana.
